Should I use magnetic or true north?
True north, which is a GPS bearing linked to the geographical location of the North Pole, works when Location Services is turned on. Magnetic north, on the other hand, depends on the Earth’s natural magnetism, which changes based on your physical location. It works when Location Services is both on and off.Click to see full…
True north, which is a GPS bearing linked to the geographical location of the North Pole, works when Location Services is turned on. Magnetic north, on the other hand, depends on the Earth’s natural magnetism, which changes based on your physical location.

Also asked, which is better true north or magnetic north?Magnetic north isn’t the same as true north — it’s close, but no cigar. Magnetic north is always moving, and we call this margin of error declination. Declination is an angle that measures the difference between true north and magnetic north. The angle varies depending on where you are on the planet.Also Know, how far off is magnetic north from true north? If you were standing on the geographic north pole holding your compass, it would point towards northern Canada at Ellesmere Island. This is a difference of about 500 kilometers between the Geographic North and Magnetic North poles! This difference is called the magnetic inclination. Similarly, does GPS use magnetic or true north? The GPS receiver natively reads in true north, but can elegantly calculate magnetic north based on its true position and data tables; the unit can then calculate the current location and direction of the north magnetic pole and (potentially) any local variations, if the GPS is set to use magnetic compass readings.Should I use True North?Although True North is recommended for all users, especially those who frequently use mapping apps over long distances, your iPhone’s GPS should be just as accurate if you’ve opted to use Magnetic North.
